I mean to RTP Header Extension. and thank you for your answer.
what I am trying to do is adding meta data per frame to a H264 RFC3984
another way which cross my mind is to put this meta data in NAL with
unspecified NAL type (24-31).
But I need it to interop with clients which dont support my meta data.
(they just need to ignore this data)
Do you think it will do the job?

		What is the proper way to imlement adding RTP extension
in Live555?

	it depends what you mean by "RTP extension".

	If you're referring to just implementing a new RTP payload
format, then this is easy - just define and implement your own
subclasses of "MultiFramedRTPSink" (for sending) and
"MultiFramedRTPSource" (for receiving).

	If, however, you're referring to implementing RTP *header*
extensions (as defined in RFC 3550, section 5.3.1), then there's
currently no clean way to do this; instead, you would need to modify the
existing "MultiFramedRTPS*.cpp" code to support this.
